1.

Install a drive pinion adjusting shim of the same thickness as
was installed prior to disassembly. Press pinion rear bearing
outer race into gear carrier, using the drift [SST: ST1713000
(

).

CAUTION:

• At first, using a hammer, tap bearing outer race until it

becomes flush to gear carrier.

• Never reuse pinion rear bearing outer race.

2.

Press pinion front bearing outer race into gear carrier, using the
drift [SST: 33230000 (J-25805-01)].

CAUTION:

• At first, using a hammer, tap bearing outer race until it

becomes flush to gear carrier.

• Never reuse pinion front bearing outer race.

3.

Press pinion rear bearing inner race to drive pinion, using the
drift [SST: ST23860000 (

)].

CAUTION:

Never reuse pinion rear bearing inner race.

4.

After checking and adjusting the tooth contact and backlash of the drive gear and drive pinion following
the procedure below.

a.

Apply gear oil to the pinion rear bearing, and assemble the drive pinion to the gear carrier.

CAUTION:

Never assemble a collapsible spacer.

b.

Apply gear oil to pinion front bearing, and assemble pinion front
bearing inner race to drive pinion. Using the drifts and stand,
press pinion front bearing inner race to drive pinion as far as
drive pinion nut can be tightened.

sembly. Set the drifts [SST: KV40100610 (J-26089)] to the right
and left. Install differential case assembly to gear carrier.

CAUTION:

• The drifts shall be placed on the center of the adjusting

shims.

carrier assembly to differential assembly. The maximum
pressure shall be 10 kN (1 ton, 1.1 US ton, 1.0 Imp ton).

• If adjusting shims are installed by tapping, gear carrier

may be damaged. Avoid tapping.

f.

tightening torque and pinion bearing preload torque.

CAUTION:

• Adjust the lower limit of the drive pinion nut tightening

torque first.

• If the preload torque exceeds the specified value, replace

collapsible spacer and tighten it again to adjust. Never
loosen drive pinion nut to adjust the preload torque.

• After adjustment, rotate drive pinion back and forth 2 to 3

times to check for unusual noise, rotation malfunction,
and other malfunctions.

9.
